m_forcenick.c

[Anthony Martinez]

>From the abusive-operator department:
m_forcenick.c seems to cause a crash on ircd-hybrid7.0.3, but not in 7.0.1...
I did recompile the module, but handle_command looks a lot like it gets a null
pointer. Is there any significant change that needs to be done to m_forcenick.c
in order to get it to work?
